Role of hormones in reproduction - SS1 Agriculture Past Questions and Answers - page 2

Prostaglandins help synchronize estrus in farm animals by causing the regression of the corpus luteum, which triggers the onset of estrus and allows for more accurate timing of breeding.

Hormones can be used to manipulate the reproductive cycle of dairy cows by synchronizing estrus, ensuring that a larger percentage of the herd comes into heat simultaneously, optimizing breeding, and ultimately improving milk production.

Superovulation is the process of stimulating a female farm animal to produce multiple ova (eggs) during a single estrous cycle. This is significant in reproductive management because it increases the potential for collecting and transferring embryos, enhancing genetic progress.

Stress can negatively affect farm animal reproductive performance by disrupting hormonal balance. Minimizing stressors through proper management, such as providing a comfortable environment and reducing handling stress, can mitigate these consequences.

Hormonal control in artificial insemination programs helps improve breeding efficiency by precisely timing insemination, ensuring that the female is in the right stage of her estrous cycle for successful fertilization. This increases the chances of conception and genetic improvement in the herd.
